Toall whom it may concern: i r

Be it known that I, \VILLrAM W; McKenvrn', a resident of Youngstown, in the'county of Mahoning and State of Ohio, have in-' vented a new and useful Improvement in Hot-Metal Cars, of which the following is a full, clear, and exact description, reference being had to the accompany n drawings,

forming part of this speei ication, 1n

Figure. 1 is an end view of a car embodying my invention; and Fig. 2, is a diagram-. matie view illustrating one of the movements of the car. i My invention has relation to hot metal or ladle cars of that type in which the ladles are emptied by pouring from a spout located at or near the top thereof. I

One object of my invention is to provide a car or ladle having a plurality of sup ports arranged to come successively into operation in tipping or dumping it, to thereby reduce the amount of drop of the, spout and in order to bring the forward portion of the spout inproper lelati'on to thereceptacle being poured into.

A further object. of m. invention is to provide'a ear or ladle of th the ladle vessel having pouring spouts (3 at opposite sides.

Secured toeach end of the car is a ladle casting 7 provided with trunnions 8, one at each side of the vertical center of the car and which normally rest in the open bearing recesses 9 of the frame 3. The casting 7' is also provided with the divergent upward extensionsor arms 10, whiehare provided at their upper portions with outwardly facing open bearing recesses 11 and .w'hieh are designed to engage. suitable fixed, bearing supports located along the track 4 adjacent to the dumping point.

is character hav-- 111g still another bearing upon which 1t cansupports is indicated at 12. Each trunnion casting is also formed at each edge with a laterally opening hearing recess 13, which, upon an extreme dumping movement, of the car in either direction, are designed to engage fi'xed' bearingprojections frame 3.

-By means of the double trunnions 8, it will be seen that the car can be tip ed in either direction, according as it is (esired to dump to the rightor to the left. .One of the fixed bearing supports 12 .is'provided wherever dumping is to take place, being located either at the let-t or right-hand side of the, track, according to the direction of dumping.

In dumping, the ladle is first turned'on one of thetrunnions 8 until such time as one of the ,open bearing recesses 11 engages the fixed bearing support 12. .Further dumping movement then takes place on the bearings 11 and 12. As this center is located outside of the track r'ails at a point near the top of 'the ladle, it: is obvious that the spout 6, will travel but a shortdistance in the complete- 14 on the ing being at a relatively low point on the 1 frame, it will be seen that the ladle can be tipped to an extreme position.

It will be obvious that instead oiproviding the several bearings on the separate ladle castings secured to the car, the car may be provided with such hearings in any suitable way. Various other changes may be made in the details 'of construction and arrangement of the parts, without departing from the spirit and scope of my invention as defined in the appended claims.

The advantages of my invention will be apparent to those skilled in the art, s nce 1 provides a'car ladle which can be tippgzd or dumped with a very short drop of the spout, and yet can be given an extreme tipped position when it is desired to remove the skull.

One of these bearing It will be understood that with this latter operation, the car is moved away from the support 12, which is notemployed in this operation.

'1. A ladle car having three sets of bearings located in different vertical planes, substantially as described.

2. A ladle car having a tilting ladle, a track upon which the car is mounted, said ladle-having a plurality of bearings locatedat different distances from its to and a truck frame having a plurality 0 bearing portions adapted to come into successive operation, together with a fixed bearing -located adjacent to the track on which the car moves, substantially as described.

3. A ladle car having a ladle provided with a lower bearing arranged at one side of the vertical center of the car, another bearing located near the top of the car, and

another bearing located intermediate the upper and lower described.

4 A ladle car having a ladle provided bearings, substantially as with "a lower bearing arranged at one side of the vertical center of the car, another bearing located near the top of the car, and

.anot-her bearing located intermediate the distances from the vertical center line of the ladle, substantially as described.

5. The combination with a-truck having bearing supports located at different distances from its center 1inc, of a tilting ladle vessel having two sets of bearings at different vertical heights and adapted to successively cooperate with the bearing supports, substantially as described. y

In testimony whereof, I have hereunto set my hand.
